MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the unit, read carefully “Safety and Precautions” and
follow these steps:
1. Switch off the power supply.
2. Slide the unit along the guides of a standard 35 mm DIN rail and fix it to the rail
by means of the black locking clip on the enclosure. Mind the correct position and
mounting dimensions shown in Fig. 1 Mounting dimensions and Fig. 2 Mounting
position.

Optional settings
To assure correct communication, the NBT needs to be activated in only two devices
on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or
Sensistant (Holding register 9).

NOTE On a Modbus RTU network, two bus terminators (NBTs) need to be activated.
VERIFICATION OF INSTALLATION
After powering the unit, the LED on the left of the RJ45 socket (Fig. 4 - 1) should
light up to indicate that the unit is supplied.
e LED on the right of the RJ45 socket (Fig. 4 - 2) indicates that there is active
Modbus communication.
If your unit does not function as expected, please check the connections.

ATTENTION e status of the LEDs can be checked only when the unit is energised. Take the
relevant safety measures!
OPERATING INSTRUCTIONS
e DRM-M-02 are entirely Modbus RTU operated. ey transfer the commands
given via holding registers 11 and 12 to change the C/O contact status.
Bootloader
anks to the bootloader functionality, the unit firmware can be updated via Modbus
RTU communication. With 3SM boot Application (part of 3SM center software
suite), ‘boot mode’ is automatically activated and the firmware can be updated.
NOTE Make sure the power supply does not get interrupted during “bootload” procedure,
otherwise you risk losing unsaved data.
